I made a mistake earlier and took the saftey out of my Yugo SKS for some detailed cleaning. Well it was a pain in the butt too get back in. Once I got it back in, the I tested the weapon with a dry fire. The hammer would only fall half way forward. So I took out the trigger assembly and re installed it again, and now it falls forward just fine. Could I had had it in there crooked? What could have caused this? I just am a little weary of something that functions wierd one minute and then ok the next. I am thinking I just had it installed crooked, or wrong the first time.
